Here is a thought for you... if TV an READING does NOT impact behavior, why do advertisers spend BILLIONS using them to do just that?

Advertisers are trying to influence behavior that is not considered bad or wrong (by most people), or at least not antisocial or illegal, example: Buy a truck. They are appealing to those who want to fit in, to look good, to have a good time, to get laid... all considered pro-social desires accepted by society.

Even those are suggestions only, and it is easy enough to decide not to buy their products: I don't care how sexy is the blonde in a beer commercial, I can easily resist buying that beer. But even if I do succumb, buying the beer isn't illegal, and won't hurt anyone (besides, possibly, my own taste buds).
